THOMAS C. JOHNSON, OF NEW HAVEN, CONNECTICUT, ASSIGNOR TO WINCHESTER REPEATING ARMS 00., OF NEW HAVEN, CONNECTICUT, A CORPORATION.

MUSHROOM-BULLET.

To all whom it may concern:

Be it known that I, THOMAS CRossLEY JOHNSON, a citizen of the United States, residing at New Haven, in the county of New Haven and State of Connecticut, have invented a new and useful Improvement in Mushroom-Bullets; and I do hereby declare the following, when taken in connection with the accompanying drawings and the characters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this application, and represent, 1n-

Figure 1, a view in side elevation of a mushroom bullet constructed in accordance with my invention. Fig. 2, a central longitudinal section, the tip with its anchor bein shown in full lines.

31y invention relates to an improvement in solid-tip sharp-nosed mushroom bullets, the object being to produce at a low cost, a bullet of superior mushrooming effect.

With these ends in view, my invention consists in a mushroom bullet having certain details of construction, as will hereinafter be described and pointed out in the claims.

In carrying out my invention as herein shown, I employ a solid conical tip, 2, formed at its inner end with a wedge-shaped or conical anchor, 33, tapering to a point, and having slightly concaved sides, though this is not essential, the said anchor being formed about midway of its length with a circumferential anchoring-rib, 4, which, with the anchor, is buried in the soft metal core, 5, which is inclosed in a sheet metal jacket, 6. As shown, a circumferential accommodation space, 7, is formed between the edge, 8, of the jacket and the inner corner, 9, of the tip, 2, the said space, 7, being filled with a circumferential band, 10, exuded Specification of Letters Patent.

Application filed September 10, 1913.

Serial No. 789,055.

from the core, 5. At the time of impact, the side walls of the tapering anchor, 3, act as a wedge to suddenly disrupt the core and jacket and spread the same outward.

I claim:

1. A sharp-nosed, mushroom bullet cylindrical at its rear end and tapering to a point at its forward end, the said bullet having a soft metal core, a jacket therefor, and a solid, conical tip projecting beyond the tapered forward end of the said jacket and continuing the exteriorlines thereof to a point, and having a wedge-shaped anchor embedded in the forward portion of the core, a circumferential accommodation space filled with. metal exuded from the core being formed between the inner corner of the projecting portion of the tip and the forward edge of the jacket.

2. A sharp-nosed, mushroom bullet cylindrical at its rear end and tapering to a point at its forward end, the said bullet having a soft metal core, a jacket therefor, and a solid tip projecting beyond the tapered forward end of the said acket and continu ing the lines thereof to a point and having a concentric, conical anchor embedded in the forward end of the said core and provided with a retaining-rib, a circumferential accommodation-space being formed between the inner corner of the projecting portion of the said tip and the forward edge of the jacket and filled with a band of metal exuded from the core and directly interposed between the corner of the tip and the edge of the jacket.

In testimony whereof, I have signed this specification in the presence of two subscribing witnesses,

THOMAS C. JOHNSON.
